   GPT-JSON – Structured and typehinted GPT responses in Python▲174

   Hey HN, I've been using GPT a lot lately in some side projects around data generation and benchmarking. During the course of prompt tuning I ended up with a pretty complicated request: the value that I was looking for, an explanation, a criticism, etc. JSON was the most natural output format for this but results would often be broken, have wrong types, or contain missing fields. There's been some positive movement in this space, like with jsonformer (https://github.com/1rgs/jsonformer) the other day. But nothing that was plug and play with GPT. This library consolidates…

   Jless, a command-line JSON viewer▲344

I'm sure many of you have some piped together some combination of cat, jq and less before; hopefully jless can replace that usage (hence the name). It supports newline delimited JSON too, so it can handle any output from jq. I built jless to…

    behold, jsonifier▲10

    Just a simple tool I hacked together last night. I wanted to paste a bunch of JSON for reference in an IRC channel, but the JSON that I wanted to paste was not formatted. I didn't quickly find a pastebin that formatted JSON for me so I just made one. It's probably so simple that it's borderline useless, but here it is! http://jsonifier.com/ example output: http://jsonifier.com/paste/4e3f84b46f3b792dde000000
